We bought the camry a few weeks ago. Aware of the issues we are fixing it. We have replaced one cv axle. Replacing the timing belt and pulleys( squeals when its turned on). For the life of me I can find this noise. Its like a tin can. Engine and trans run great. If you refernce what it might be or is please tell me where about to look.

 

tin can like metal to metal ?
when motor running and driving ?

my thoughts
check exhaust heat shields
or if its a loose baffle in the catalytic converter or the muffler

 

​​​​​​​Like a rock in a can noise

 

rock in a tin can.. gee

you may have wait till after the timing belt and water pump are done

one suggestion for now
take the serp belt off and start the motor
doing that will cross a few possibles causes off the list

if the noise isnt there it s something easily replaceable

 

It doesnt do it all the time. Sometimes when i start to accelerate and slow down. It will make a noise about 30 seconds and thats it. And then some days I hear nothing.
